What is a true statement regarding measuring and transferring pesticides?

The correct answer highlights an essential practice in pesticide application that enhances safety and effectiveness. Rinsing the measuring container after use and pouring the rinse water into the spray tank ensures that no pesticide residue is wasted and that the full intended dosage is utilized. This practice also minimizes environmental contamination by ensuring that all pesticide material is accounted for in the mixture being applied.

When you rinse out the measuring container and add that rinse to the tank, it contributes to the overall concentration of the pesticide in the spray solution, allowing for a more precise application as per label instructions. This is an important step because it helps to ensure compliance with environmental regulations and promotes responsible pesticide use.

Furthermore, the other options address practices that are either incorrect or less effective. Measuring pesticides in direct sunlight can lead to discrepancies in measurement due to temperature changes affecting the volume of the liquid. Disposing of the container immediately after measuring may lead to improper disposal methods or missed opportunities for cleaning residual pesticides, which poses risks to both handlers and the environment. Using separate containers for different pesticides is a good practice to avoid contamination; however, this is not specifically related to the immediate process of measuring and transferring pesticides as described in the selected choice. Thus, option C stands out as the most appropriate guideline for safe and
